Effect of androgen deprivation therapy on arterial stiffness and serum lipid profile changes in patients with prostate cancer: a prospective study of initial 6-month follow-up.

To explore arterial stiffness during the administration of androgen deprivation therapy (ADT) in patients with prostate cancer (PCa), a new indicator, the cardio-ankle vascular index (CAVI), and serum lipid profile changes were monitored.

A prospective study assessed the changes in arterial stiffness using the CAVI and clinical laboratory variables among 58 men with prostate cancer treated with ADT for 6 months. Furthermore, patients who had a high risk of developing arterial stiffness after ADT were investigated.

The whole cohort had no significant increase in arterial stiffness within 6 months after ADT, but 55.2 % of patients had an increased CAVI. Serum levels of total cholesterol, high-density-lipoprotein cholesterol (HDL-C), and low-density-lipoprotein cholesterol (LDL-C) increased significantly at 1 month after the start of ADT and maintained high values thereafter. At baseline, HDL-C was lower and LDL-C and LDL-C/HDL-C were higher in the group with than without an increased CAVI after 6 months of ADT administration.

Although the whole cohort did not show a significant change in arterial stiffness with ADT, some patients showed an increased arterial stiffness monitored with the CAVI. The balance between LDL-C and HDL-C, or LDL-C/HDL-C, might have an impact on the development of arterial stiffness after ADT administration. Thus, clinicians might be able to monitor PCa patients who have a high risk of development of arterial stiffness after ADT administration by referring to LDL-C/HDL-C levels.
